Job Title: Senior Product Development and Process Engineer | Req : 17618| HR Contact: Christina G WHITE| Location: Building Envelope - Fishers, IN

ABOUT THE ROLE

We are seeking a high-caliber Senior Product and Process Development Engineer to lead the lifecycle development of next-generation commercial roofing systems. In this role, you will blend deep polymer science and engineering fundamentals with hands-on manufacturing and customer insights. You will design, model, test, and scale advanced roofing solutions—specifically focusing on TPO, EPDM, and Polyisocyanurate (ISO) materials—while bridging the gap between R&D, plant operations, and field performance.

WHAT YOU'LL ACCOMPLISH

• Lead the conceptualization, design, and development of commercial roofing products and full-assembly systems from inception to commercialization.
• Apply a systems-engineering approach to ensure components (membranes, insulation, adhesives, and fasteners) perform cohesively under diverse environmental stresses.
• Translate market trends and customer pain points into concrete, innovative technical solutions.

Advanced Modeling & Experimental Testing

• Leverage CAE tools (FEA/CFD) for structural,thermal, impact, and wind-uplift performance simulations, or for process simulations to accelerate product development and plant troubleshooting.
• Design and execute rigorous physical testing protocols (e.g., tensile, tear, accelerated weathering, thermal efficiency) to validate FEA models and ensure compliance with industry standards (FM, UL, ASTM).

Material & Process Engineering

• Leverage deep technical expertise in polymer chemistry, structure-property relationships, formulation design, and compounding.
• Optimize the processing of single-ply membranes (TPO, EPDM) and rigid foam insulation (ISO), ensuring robust blending, extrusion, and curing/foaming performance.
• Troubleshoot complex plant processing issues related to polymer rheology, degradation, and raw material variability to eliminate defects and improve yields.

Voice of Customer & Cross-Functional Leadership

• Act as a technical bridge to the field, capturing customer feedback to refine product designs and resolve complex field performance issues.
• Collaborate closely with Product Management, Operations, Quality Assurance, and Procurement to drive projects to completion on time and within budget
• Demonstrate a commitment to communicating, improving and adhering to health, safety and environmental policies in all work environments and areas.
• Promote a culture of…
